Victor Wembanyama returned from a calf injury and energized the Spurs in Las Vegas, scoring 22 points (9 rebounds, 2 assists, 2 blocks) and delivering key plays that helped San Antonio beat the Oklahoma City Thunder 111-109 to reach the NBA Cup final against the New York Knicks.Oklahoma City — 24-2 this season and fresh off a 16-game winning streak that ended — shot a season-low 41 percent and 9 for 37 from three, and coach Mark Daigneault and MVP Shai Gilgeous-Alexander said the narrow loss is a chance to learn ahead of two heavy rematches with San Antonio later this month.
